Check each set that includes the number shown.

natural numbers
whole numbers
intergers
rational numbers
irrational numbers
real numbers

Fourth option.

Sixth option.

Step-by-step explanation:

We know that:

- Any number you can find on the number line, is a Real number.

- Integers contains positive numbers, negative numbers and zero. Every Integer is a Rational number.

- A Rational number is that number that can be written in the following form:

Where "a" and "b" are integers ().

- An Irrational number cannot be written as a simple fraction.

- A Whole number is any of the numbers {}. Every Whole number is a Rational number.

- Natural numbers contain  the set of positive integers{} or to the set of nonnegative integers {}, Every Natural number is a Rational number.

 Based on this, since is in the form where and , it is a Rational Number and therefore a Real number.

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
